This one is certain. Not since the 1920s, Only at sites within campgrounds in the Valley and Tuolumne Meadows. And even within those campgrounds, you're still going to come up against strict limits on the number of people, or be limited to only sites specifically designated for larger groups.

It's a fun way to get thrown out of the park... fined... even jailed. They have a jail, btw, right there in the Valley. But no, you can't camp just anywhere. I bet they'd let you spend the rest of the night in a cell tho.

My dad got a speeding ticket once - the alternator wasn't charging the battery and we were trying to bust it for home, and he had fun trying to get the ranger to understand why he couldn't comply with shutting off the engine. "Sir, if you have jumper cables and agree to help me start it again..."

He just paid the ticket, didn't go to court. Speeding in a panic is still speeding. And that was a long time ago before they were really expensive. These days, you don't speed in the park, you sit there in long lines of cars waiting to get somewhere...
